I want to be able to email an Excel invoice and make sure it cannot be
changed by the customer. How is this done?

you can use the protection tool, go to the "tools" menu, choose "protection"
and then "protect worksheet". then enter a password and that's it!!

You can't do it.

Worksheet protection is easily broken.

You may want to use a different document type (.pdf or some kind of image). But
even those can be edited...
